SPECIFICATION forming part of Letters Patent No. 654,296, dated July 24, 1900.

Applicationifiled December 19, 1899. Serial No. 740,930. (No model.)

To all whom it may concern:

Be it known that I, LOUIS D. VOGEL, a citizen of the United States, residing at Omaha, in .the county of Douglas and State of'Nebraska, have invented a new and useful VVoodworking-Machine, of which the following is a different sizes and shapes of wooden vessels.

A further objectis to provide a cutter-carrying mechanism which may be adjusted quickly toward or from the work, so as to permit the latter to be applied to or removed from the work-head without hindrance from the cutter mechanism, and to also provide for a proper movement of the cutter mechanism into operative relation to or engagement with the work.

A further object is to provide means for regulating the adjustment of the cutter mechanism within certain fixed limits, according to the size or diameterof the work under treatment; but this limit of adjustmentis variable under certain changes in the operating de vices to the end that the cutters may be adjusted properly to work which varies in diameter.

With these ends in view the invention consists in the novel combinations of mechanisms and in the construction and arrangement of parts comprising such mechanism, as will be hereinafter fully described and claimed.

In the accompanying drawings 1 have represented a woodworking-machine which embodies the several features of my invention in their preferred form, and to these drawings I shall now refer in order to explain more clearly the nature of the invention and the manner in which the same is or may be carried into effect.

Figure 1 is a plan view of a woodworkingmachine embodying my invention. Fig. 2is an elevation of the machine looking at the side on which the drop-weights are located. Fig. 3 is a vertical transverse section through the machinein the plane of the dotted line 3 3 on Fig. 1. Fig. 4 is a detailtransverse sectional elevation through one of the transversely-movable carriers and parts associated therewith, the plane of the section being in the line 4 4t of Fig. 1 looking in the direction of the arrow. Fig. 5 is an enlarged detail sectional elevation in the planeof the dotted line 5 5 of Fig. 2, illustrating the verticallyslotted hanger serving as the guide for the cord-operating pulleys that advance the iongitudinally-movable cutter-carriers and operate the expansible cutter heads, respectively. Fig. 6 is a detail face view of the parts shown by Fig. 5. Fig. 7 is an enlarged view, in end e1evation,of the expansible workhead; and Fig. 8 is a detail sectional elevation of said work-head, taken in the plane of the dotted line 8 8 on Fig. 7. Fig. 9 is aplan view, on enlarged scale, of the pair of opposin g cutter-heads to illustrate the several trimming, howeling, and crozing knives, said View also showing the position assumed by one stave of a package when the latter is in operative position relative to the cutters. Fig. 10 is a perspective view of one cutter-head and a part of its carriage detached from the machine. Fig. 11 is a similar view of the other cutter-head. Fig. 12 is a detail vertical sec tion in the-plane of the dotted line 12 12 on Fig. 9 and taken through the cutter-head which is provided with the crozing-knives. Fig. 13 is a detail perspective view of a stave treated and finished by the machine of my invention.

The same numerals of reference are used to indicate like and corresponding parts in each of the several figures of the drawings.

The horizontal bed or frame 10. of my wood-' working-machine may be of any suitable construction adapted to support the several working parts embodied in the construction of the machine; but at a point intermediate of its length this bed or frame is provided with a cross-rail 11, on the upperedge of which is secured the bearing or cap-box 12, which forms one of a series of bearings (not shown) provided in the machine for the support of the horizontal driving-shaft 13. This shaftis arranged in an elevated position longitudinally of the machine, so as to lie above and centrally with relation to the bed, and to an end portion of this shaft is fitted an ordinary clutch-pul-.

ley 14: and a stepped or cone pulley 15, said pulleys adapted for the provision of an ordinary driving-belt and means for starting and stopping the shaft, whereby the work may be rotated at variable speeds and the machine thrown out of or into operation at will. This shaft carries a work-holding head which in its entirety is indicated by the numeral 16 in the drawings. This head is skeletonized for lightness in construction, and it is of sectional form to render its parts adjustable for the purpose of expanding or contracting certain elements of the head in order to vary the size and external contour of said head, and thereby adapt the same to the reception of articles which may vary in size and shape. It is to be understood that this rotary head is adapted for the reception of tubs, pails, or other wooden articles which are essentially circular in cross-section but the expansible work-head has its parts adjusted so that it is immaterial whether the articles to be operated upon are cylindrical or conical in form. As a matter of fact, however, nearly all of the articles to be treated by my machine are of a conical contour more or less-thatis to say, they taper longitudinally or vary in diameter at theiropposite ends-while at the same time they are circular in cross-section, it being understood that the embodiment of the invention shown by the drawings is especially adapted for appear.

treatingbutter packages, pails,and analogous wooden vessels. For this reason I have shown the expansible head as essentially of conical form; but it is to be understood that this head may be adjusted for the reception of cylindri'cal articles and that the dimensions and form of the head may be varied within wide limits to suit the different articles or devices which it may be desired to operate upon in the machine. This expansible head embodies in its construction the disks 17 18, each provided with a collar or hub 19, the latter having the binding-screw 20, and these disks are fitted on the shaft 13 in parallel relation to each other and at a suitable distanceapart, the clamping-screws being set against the shaft to make the disks fast therewith. Each disk is provided in its outer face with a plurality of dovetailed grooves 21, which are disposed radially to the imaginary axis of the disk, and the two disks 17 18 carry the two series of radially-disposed arms 22 23, respectively, said arms being fitted in the dovetailed grooves so as to project beyond the peripheral edges of the disks and adapted to slide thereon. The expansible head shown by the accompanying drawings has the disk 17 of greater diameter than the disk 18, and the arms 22 of said larger disk extend beyond the outer ends of the arms 23 on the smaller disk 18 for a purpose which will presently Any suitable means may be provided for clamping each series of arms firmly in place on its disk; but I prefer to employ longitudinal slots 2i in the arms and the bolts 25, which pass through the disk and the slots tions wherein the arms of one series extend outwardly beyond the arms of the other series enables a series of bars 26 to be employed,

which converge toward one end of the head.

These bars lie longitudinally of the head, beyond the circumference of the disks thereof, and are suitably spaced apart to assume positions corresponding to the arms of the two series on said disks, and each longitudinal inclined bar 26 is connected to a pair of the arms 22 23 by means of the pivotal joints 27. It is therefore to be understood that each bar 26 is supported by a pair of arms attached to the respective disks of the head, and the pivotal connection between the individual radially-adjustable arms and the bar enables the arms to be extended more or less beyond the disks in order to give the proper inclination to the bars 26 individually or the convergence of the bars collectively with relation to the axis of the head. The improved construction of the head enables the same to vary for the dual purpose of changing its external contour and the diameter at opposite ends thereof, and this change in the physical characteristics of the head is effected by a few easily-performed adjustments of the parts comprising the head, whereby articles of different dimensions and contours may readily be fitted on the head by slipping the article endwise over the smaller end of same. It is to be noted that the longitudinally-converging bars 26 operate to bind against the inner surface of the cross-sectionally-circular and longitudinally-tapered article, so that the latter will be clamped frictionally on the head, whereby the article is made to rotate with the head when the shaft 13 is in motion.

28 29 designate transverse guides,which are arranged in horizontal positions on one side of the bed or frame 10 to extend outwardly therefrom. These guides are arranged parallel to each other in planes on opposite sides of the work-head 16, as shown by Figs. 1 and 2, and said outwardly-extending guides are braced into position by the inclined struts 30, which are fastened to the guides and a side rail of the bed or frame 10. (See Figs. 2, 3, and 4:.) Each guide consists of two members or parts, which are braced by a corresponding number of struts; but the'detailed construction of these parts is not material.

In my machine I employ two cutter-heads, which are adapted to be presented to the opposite end portions of the work to be operated upon, one cutter-head being equipped with knives which trim the end edge of the work and the inner and outer faces of the staves thereof, while the other cutter-head is equipped with a plurality of knives which are fashioned and arranged to croze the inner surface of the work adjacent to the edge,

to howel the staves, and to trim the'end edges of the staves, all as will hereinafter appear. These two cutter-heads are capable of a compound movement with respect to the workhead-that is to say, the cutter-heads are capable of a movement longitudinally of the machine and simultaneously in opposite directions in order to advance said heads toward or from the article on the work-head and said cutter-heads are also capable of a simultaneous movement transversely to the axial plane of the work-head in order to move the cutter-heads laterally to and from the article on the work-head for the purpose of moving the cutter-heads out of operative position, so that the work may be placed on or removed from the work-head without hindrance from said cutter-heads. The transverse movement of the cutter-heads is effected by the employment of slidable carriers 31 32, which are fitted, respectively, in the guideways 28 29. (See Fig. 1.) These carriers are in the form of horizontal slides, which are free to move in the guideways 28 29 in a direction transverse to the machine and toward or from the work-head, the axis of which is common to the longitudinally-arranged driving-shaft 13. Said slidable carriers are provided near their inner ends with the guideways 33, (see Fig. 4,) said guideways being arranged at right angles to the axis of the transversely-movable carriers, and thus lyingin the direction of the length of the machine. In the' guideways 33 of the transversely-movable carriers are slidably confined the cuttercarriers 34 35, the latter being arranged and movable in said guideways longitudinally of the machine, so as to travel toward or from the ends of the article on the work-head. It is therefore to be understood thatthe slidable carriers 31 32 move the cutter-carriers transversely across the machine and laterally with respect to the work-head; but these cutter-carriers are capable of a slidable movement in the guides 33 in the direction of the length of the machine. 'lhecutler-carriers3435arenormally drawn away from each other and from the end portions of the article on the work-head by means of weighted cables 36, each cable being fastened securely to an arm 37, which is fastened to the front end of the cutter-carrier. The cable is guided around one member of a double sheave 38 39, pivoted on one .transversely-movable carrier 31 or 32 and around a sheave 38 on a fixed guide for said carrier, and thence around a sheave 40, which is mounted on a fixed arm 41 of the framework. Eachcableforthelongitudinally-movable cutter-carrier is guided by the sheaves described, so as to be out of the way of other operating'parts of the machine, and a dropweight 42 is fastened to a depending length of this cable 36, the tendency of the dropweights of the two cutter-carriers being to normally pull said cutter-carriers away from each other.

article under treatment in the machine.

A depending arm 43 is fastened securely to each transversely-movable slide, so as to lie between the pair of inclined struts 30, and to the arms of the respective slides 31 32 are individually fastened the cables 44, each having a drop-weight 45, whereby the weighted cables normally pull on the slides or carriers 31 32 to move the latter and the devices mounted thereon in a direction transversely across the machine and laterally and away from the work on the work-head. Each cable 44 passes over a sheave 46, which is loosely journaled on an arbor 47, supported in the inclined struts 30, provided for bracing the members of the guideway for the transversely-movable carrier to which the cable is attached.

I have provided means for simultaneously moving the transversely-movable carriers 31 32; but such means is connected individually and adj ustably to the arms 43 of said car riers in a manner to provide for variation in the position of the slides and the cutter-heads thereon, so as to compensate for the variation in the diameter at opposite ends of th: pair of slidable bars 43 are fitted in suitable openings or slots 49 in depending rails of the horizontal frame or bed l0,'said bars being arranged in overlapping relation to the depending arms 43 of said carriers 31 32. The bars are supported in the frame or bed to be movable in rectilinear paths across the same, each bar having a series of apertures 50, in either one of which may be fitted a connecting-pin 51, that serves to'fasten the depending carrier-arms 43 adj ustably to the slidable bar 48. A connecting-bar 52 is fastened to the slidable bars 48, so as to insure simultaneous movement to the pair of bars 48, and as the arms 43 are attached to the slidable bars and to the transverselymovable carriers 31 32 it is evident that the motion of the bars 48 will be communicated by the arms 43 to the carriers 31 32, although said carriers may be adjusted individually on the bars by means of the pins 51. A coiled spring 53 is fastened to a suitable part of the frame or bed and to the-connecting-bar 52, and this spring tends to norm ally draw the connectingbar in the same direction that the drop: weights 45 pull the carriers 31 32; This spring is arranged centrally with relation to the connecting-bar so as to exert stress thereon in-a manner which prevents binding of the parts in a practical operation of the machine. An ad justing-cable 54 is fastened to the-con necting-bar 52 in any suitable way, and this cable is associated with hand-operated adjusting devices adapted to move the connecting-bar 52 and the carriers 31 32 against the tension of the retracting-spring '53 and the gravity of the drop-weights 45, whereby the carriers 31 32 and the cutter devices thereon may be drawn toward the article on the work-head. An arbor or spindle 56 is journaled in any suitable way on one side of the machine frameor bed and a drum or sheave 57 is mounted on this arbor, the cable 54 being fastened in any suitable way to the sheave. (See Fig. 3.) Aseries of transverse openings 58 is provided in the sheave 57, in either one of which may be fitted a connecting-pin 59 for the purpose of adjustably connecting a lever 60 to the sheave, said lever being fitted loosely on the arbor or spindle 56, so that its axis of movement is coincident with the axis of the sheave. It will be seen that the pin connects the lever adjustably with the sheave in a manner to make the sheave turn with the lever when the latter is operated by hand in order to draw on the cable 54'and adjust the bars 48 and the slidable carriers 31 32, and this lever is equipped with a latch 60, which may fit in any one of the series of notches in a segment 61, that is fastened securely to a side of the machine bed or frame, whereby the lever may be locked in place in order to confine through the intermediate mechanism the slidable carriers in their adjusted positions with relation to the work-head.

62 designates a vertical hanger which is securely fastened to a side of the machine-bed in a position equidistant from the transverse guideways 28 29, and this hanger extends below said bed and above the upper face thereof. (See Figs. 2 and 3.) The hanger is provided with a longitudinal slot 63, adapted for the accommodation of the adj Listing-levers 64 65, the former of which operates devices that tend to move the cutter-carriers longitudinally of the machine and inwardly toward the end portions of the article on the work-head, while the last-named lever 65 actuates devices that close the jaws of the sectional cutter-heads upon the end portions of the article subsequent to the inward movement of the cutterheads toward each other and said end portions of the article. The lever 64 is fulcrumed in a suitable way on the outside of the machinebed, so as to have one end extend through the slot in the lower part of the hanger, and this end of thelever is connected to a sheave-block 66, in which is supported the spindle for the sheave 67. On the hanger 62, near its upper end, is loosely j ournaled a pair of idle guidesheaves 68, which are supported on horizontal pins attached to the hanger so as to have their opposing edges disposed on opposite sides of the vertical axis of said hanger. A carriage-operating cord is fastened at one end to an arm 71 on the cutter-carriage 35, from thence passes over one guide-sheave 68,

thence passes downwardly and beneath the sheave 67, which is movable with the ad justing-lever 64, thence passes upward ly and over the other guide-sheave 68, and is finally extended to an arm 72, which is made fast with the other cutter-carriage 34. It is obvious that the end portions of the cord 70 are fas- ,tened to the cutter-carriages, while the inter- 77, the latter having a part 77 thereof fitted in the guid eway 78 of the hanger 62. On this sheave-block is supported the arbor of a cordoperating sheave 79, the latter being arranged above and in a vertical plane to one side of the sheave 67 for the carriage-cord 70. The pair of small sheaves 80 are journaled on the upper extended part of the hanger, so as to lie above the sheave 79 and the guide-sheaves 68 for the carriage-cord, for a purpose which will presently appear.

In my machine I employ cutter-heads of sectional construction, each head adapted to have its jaws or members opened and closed in order that the cutters may be spread for the purpose of permitting the end edge of the work to enter the space between the jaws. The jaws for the cutter-head on the carriage 34 are indicated by the reference-numerals 81 82, while the jaws for the cutter-head on the other side of the cutter-carriage 35 are indicated by 83 84. Each cutter-head has its curved jaws connected by a link 85, which has its end portions pivotally attached at 85 to the jaws and to the cutter-carriage, thus confining the jawson said carriage in a manner which permits said jaws to be opened and closed. The shanks of the jaws are extended beyond the pivotal connection with the links for the reception of a spring 86, which operates normally to separate the ends of the jaws on which the cutters are mounted, and between the shanks of these jaws is disposed acam 87. A bolt 88 confines the cam on the cutter-carriage, and the cams for the two outter-heads are actuated by levers 89 90. A cord 91 is fastened to thelever 89 and extends over one of the sheaves 80, around the sheave 79, which is actuated by the lever 65, thence upwardly to and around the other sheave 80, and is then fastened to the lever 90. By operating the lever 65 to depress the sheaves 79 the cord 91 is strained to move the levers 89 9O inwardly toward each other in the direction indicated by the arrow in Fig. 1, and the cams 87 are thus operated to spread the shanks of the jaws against the tension of the retracting-spring 86 for the purpose of closing the jaws and the cutters upon the work. It is obvious, however, that the jaws of the cutterheads should remain in their open or spread conditions until the carriages 31 32 shallhave been moved toward the work-head and the cutter-carriages, with the cutters thereon, shall have been drawn inwardly toward the end portions of the article on the work-head.

Before proceeding to a description of the construction and arrangement of the knives I will first describe the stave in its finished condition after treatment by my improved machine, said stave being shown by Figs. 9 and 13 and being representative of each of the other staves which when assembled in proper relation constitute the package or article which is fitted on the work-head for treatment in the machine. Itis to be understood that the staves are assembled in circular series and in an unfinished condition to produce the body of the package which is to be fitted upon the work-head, and said unfinished staves of the package are treated simultaneously during the rotation of the workhead, so as to have the faces and edges of the staves finished, as shown by Figs. 9 and 13. This stave is indicated at 120. On the inner face of the stave, at one end thereof, the stave has the howeled curved surface 121, and the croze 122 is cut transversely across this howeled inner surface of the stave. The end edge of the stave, at the howeled portion thereof, is trimmed, as at 123, and the opposite end edge of the stave is also trimmed at 124, thus producing smooth finished edges at opposite ends of the stave. At the end of the stave opposite to the howeled surface 121 the inner face of said stave is beveled or curved at 125,and the outer face of the stave is curved, as at 126, the end edge 124: of the stave being trimmed between these beveled or curved surfaces 125 126. From this description of the stave it will be apparent that a plurality of knives or cutters on the two cutter-heads 1n ust be employed for the proper operation on the inner and outer surfaces and the endedges of the staves, and Ihave fulfilled this condition by a simple and efficient arrangement of knives, which are arranged in a novel manner so as to be properly presented to the appropriate faces and edges of the package.

The cutter-carriage 34 is equipped with the crozing-knives, the howeling-knife, and a trimming-knife suitable for forming the bowel 121, the croze 122, and the trimmed edge 123 on the staves of a package,at one end thereof. This carriage 34 is provided between the free ends of the jaws 83 84 with a fixed knife-block 92, which extends above the horizontal plane of the jaws, and this knife-block is provided with a seat-face 93, the same being inclined downwardly toward the plane of the carriage. On this knife-block is fitted the edgetrimming knife 95, which is held firmly in place by a set screw 97 or other suitable clamping device, whereby the edge-trimming knife is held in a position inclined to the plane of rotation of the work. This inclined knife has its cutting edge 08 inclined to the longitudinal axis of the knife-body, and said knife may be projected more or less beyond the knife-block, so as to make its cutting edge 98 operate with a draw out on the end edges of the staves. The knife-block 02 is provided with a recess 99, in which the jaw 84 of the cutter-head is free to move in order to approach and r'ecede from the complemental other jaw of the cutter-head, and this jaw 84: is also provided atits free end with an abutment 110, which is adapted to bear frictionally against the outer surface of the pack? age when the two jaws of the cutter-head are closed in order to properly present the knives or cutters to one end of the package. The other jaw 83 of this cutter-head on the carriage 345 is provided at its free end with a' knife-block 100, which is disposed in the horizontal plane of and in opposing relation to the abutment 110 on said jaw 84:, and this knife-block is integral with the jaw 83 or is firmly fastened thereto, so as to move therewith. The knife-block 100 is provided on its upper face with an inclined seat 101, and said knife-block is furthermore provided with a transverse slot 102. The howeling-knife 103 is fitted laterally against the inclined seatface 101 of the movable knife-block, so as to be presented to the work in an inclined position, said knife being held firmly in place by a clamp 104, which is shown in the form of a binding-screw. The howeling-knife 103 is provided with the curved cutting edge 105, and this howeling-knife is movable with the jaw 83 and the knife-block 100, so as to be carried thereby into overlapping relation and above the edge of the edge-trimming knife 95. The howeling-knife is thus presented in an inclined position to the inner surfaces'of the staves at one end of the package, and the curved edge 105 of this knife is operable'on the staves to produce the howeled surface 121 thereon, I employ a pair of crozingknives 106 107, which are fitted in the slot 102 of the movable knife-block, and these knives have their inner beveled ends 108 ex tended beyond the inner face of this knifeblock, so as to lie below the cutting edge of the howeling-knife 103 and opposite to the working edge of the edge-trimming knife 95. The crozing-knives are held in place within the slotted knife-block by a suitable clamp 109, and these knives may be individually adjusted in order to project them for proper distances to cut the croze 122 in the staves. It is to be observed that the howeling and crozing knives are both carried by one jaw of the cutter-head on the carriage 34, while the edgetrimming knife is on the carriage itself, and the other jaw of the cutter-head is provided with an abutment 110, which is opposite to the howeling and crozing knives. When the cam is turned in line with the jaws, the'spring closes the shanks together and opens the work ing ends of the jaws, so as to separate the abutment 110 and the crozing and howeling knives laterally, thus permitting the ends of the staves in the package to be received in the space between the abutment and the said knives on the movement of the carriage 3431;0- ward the work on the revoluble head, after which the cam is operated in a manner to close the jaws for the abutment to bear against the outer surface of the package, the crozing and howeling knives to operate on the inner surface of the staves, and the edge-trimmin g knife to cut the end edges of the staves. The other cutter-carriage 35 is provided with a knife-block 111, having the edge-trimming knife 112, similar to the knife-block 92, and the knife 95 on the carriage 34. The jaw 82 of this cutter-head on said carriage 35 is provided with a lug 113, forming an inclined seat for a beveling-knife 114, the same being held in place bya suitable clamp 115. This beveling-knife has its working edge presented in an inclined position to the outer face of the staves at the other end of the package. The jaw 81 of said cutter-head on the carriage 35 is. provided witha short post 116, having an inclined seat-face 117, and on said seat-face is fitted the howeling-knife 118, the latter being clamped in place and having the curved cutting edge 119. The knives 118 114 operate on the inner and outer faces of the staves in the package, so as to produce the inner and outer curved surfaces 125 126, and it is to be observed that the jaws 81 82 of the cutter-head on the carriage 35 are provided with the face trimming and howeling knives, respectively, which are adapted to approach each other and the work when the jaws are closed by the action of the cam.

The operation maybe described as follows: The work is forced on the revoluble head, so as to rotate therewith. The operator first adjusts the lever to move the slides 31 32, the. cutter-carriages, and the cutter-head laterally across the machine until the cutterheads are in line with the package, the jaws of the cutter-heads being open. The lever 64: is now manually operated to strain the cord and move the cutter-carriages toward each other until the ed ge-trim ming knives thereon are in position to work' on the end edges of the staves, and, finally, the lever 65 is manually operated to draw on the cord 91 and move the arms 89 90, so as to operate the cams and simultaneously close the jaws of the two cutter-heads, whereby the howclingknife 103 and the crozing-knives on the cutter-head of the carriage 31 are operatively related to the inner surface of the staves at one end of the package, and the beveling and howeling knives on the cutter-head of the carriage 35 are brought into proper position for operation on the inner and outer surfaces of the staves at the other end of the package. These knives serve to howel, croze, finish, and trim the staves to reduce them to the condition shown by Fig. 13 at one operation in the machine. Previous to removing the work the carriages are retracted and moved laterally, and the revoluble head is then arrested.

It will be understood by reference to the drawings that the levers 6O 64 65 are within convenient reach of the operator stationed on the side of the machine opposite the carriages and cutter-heads and that said levers are manually operated when the machine is in use.

Changes in the form and proportion of parts may be made without departing from the spirit of the invention.

Having thus described the invention, what I claim is 1. The combination of a revoluble workhead, a pair of carriages movable at right angles to the axis of the work-head, connections to simultaneously move said carriages, cutter-heads on said carriages, movable toward and from each other, connections to simultaneously move said cutter-heads, a pair of pivoted jaws on each of said cutter-heads,

the jaws of each of said pairs having workengaging faces and howeling-knives and connections to simultaneously close the said pairs of jaws, substantially as described.

2. The combination with a revoluble workhead, of transversely-movable carriages, connections between said carriages to move the latter simultaneously, said carriages being adjustable independently of each other on said connections, work heads on said carriages, and movable toward and from each other, and connections to move said workheads simultaneously, substantially as described.

3.
